    Bismuth is without doubt a heavy metal; It occurs so low in the periodic table many were puzzled by the fact that it didn't seem radioactive. In fact its major isotope bismuth219 was predicted to be so back in 1949. But it wasn't until 55 years later, when the French physicists finally observed its decay.

  • Bismuth: The mineralogy of Bismuth

    Most widespread minerals containing Bismuth; This list of minerals containing Bismuth is built from the locality database. This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rockformingminerals so it does not give an undistorted distribution of Bismuth mineral species.

    We present and discuss on bismuth oxide films grown on costefficient BK7 glass slides by pulsed laser deposition using a metallic target. Our choice is of particular interest due to the high number of intermediate bismuth oxides that can form during the oxidation process, along with the polymorphs of the stoichiometric oxide, bismuth trioxide (Bi2O3). We show that the oxidation degree of ...
